Shamir's Secret Sharing for teams
Split a secret into key portions and give each portion to a different person. No single person can recover the secret alone—only when enough key holders come together can the secret be reconstructed.
Use Create share to split a secret (no account needed). Use Decrypt to recover a secret from key portions. Log in to create organizations, invite members, store secrets, and request decryption from your team. New here? See how it works →
